The ability to properly resolve end-tidal values can be measured by using the set-up described in ISO
80601-2-55:2011 figure 201.101. In short, the method consists of sampling gas from two different
sources connected to an electrically controlled pneumatic valve to permit rapid switching between
the two sources. During the test, the valve is set to switch gas source at a number of frequencies
(simulating the range of specified breath rates) and for each frequency the end-tidal value presented
by the gas analyzer is noted. From a diagram of end-tidal value over frequency, the frequency at
which the gas analyzer is no longer able to resolve end-tidal values according to specification is
identified. This ability to properly resolve end-tidal values is listed in the corresponding AIONâ„¢
Multigas Analyzer technical specification.
